Examples with VectorView org.apache.ignite.ml.math.primitives.vector.impl.VectorView used on opensource projects

Example 1 with VectorView

use of org.apache.ignite.ml.math.primitives.vector.impl.VectorView in project ignite by apache.

the class VectorViewTest method setup.

/**
 */
@Before
public void setup() {
    parentVector = new DenseVector(MathTestConstants.STORAGE_SIZE);
    IntStream.range(0, MathTestConstants.STORAGE_SIZE).forEach(idx -> parentVector.set(idx, Math.random()));
    parentData = parentVector.getStorage().data().clone();
    testVector = new VectorView(parentVector, OFFSET, VIEW_LENGTH);
}

Example 2 with VectorView

use of org.apache.ignite.ml.math.primitives.vector.impl.VectorView in project ignite by apache.

the class VectorViewTest method testWriteReadExternal.

/**
 */
@Test
public void testWriteReadExternal() throws Exception {
    assertNotNull("Unexpected null parent data", parentData);
    File f = new File(EXTERNALIZE_TEST_FILE_NAME);
    try {
        ObjectOutputStream objOutputStream = new ObjectOutputStream(new FileOutputStream(f));
        objOutputStream.writeObject(testVector);
        objOutputStream.close();
        ObjectInputStream objInputStream = new ObjectInputStream(new FileInputStream(f));
        VectorView readVector = (VectorView) objInputStream.readObject();
        objInputStream.close();
        assertTrue(MathTestConstants.VAL_NOT_EQUALS, testVector.equals(readVector));
    } catch (ClassNotFoundException | IOException e) {
        fail(e.getMessage());
    }
